Given numbers are 255, 813, 550, 870

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 813 are 3 x 271

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 870 are 2 x 3 x 5 x 29

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 255, 813, 550, 870

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(255, 813) = 69105

GCD(255, 813) = ( 255 x 813 ) / 69105

= 255 / 813

= 255

Step2:

LCM(3, 550) = 1650

GCD(3, 550) = ( 3 x 550 ) / 1650

= 3 / 550

= 3

Step3:

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

= 1 / 870

= 1

So, Greatest Common Divisor of 255, 813, 550, 870 is 1
